Preventing moisture damage to paper rolls during container transport

Paper is naturally hygroscopic and absorbs moisture very quickly from the ambient air. In closed containers, even normal day-night temperature fluctuations can cause air humidity to rise sharply and condensation to form—with significant consequences for sensitive paper rolls.

Challenge: moisture penetration and quality loss during transport

For one of our customers, condensation forming in the container led to soaked sections on several paper rolls. These had to be removed before further processing at the recipient in China, causing time, material, and cost losses. Paper absorbs moisture very quickly and immediately loses its processability—even individual damp spots can compromise entire roll batches.

Solution: Absorption of Air Humidity in the Container Using SeaDry

To protect the sensitive paper rolls throughout the entire transport duration, the use of the high-performance desiccant SeaDry, specially developed for containers and manufactured in Germany, is recommended. It sustainably reduces air humidity in the container, even during long transport routes exceeding 60 days, prevents condensation, and thus effectively protects the hygroscopic paper rolls from moisture damage.

Result: Dry Paper Rolls and Reliable Quality at the Recipient

Numerous companies from the paper and packaging industry are already successfully using SeaDry in their global logistics chains. In the case described, moisture ingress was reliably prevented. Thanks to various designs, sizes, and mounting options, SeaDry can be flexibly adapted to any transport configuration. Furthermore, the extensive ThoMar range reliably covers additional production and logistics steps.
